Jeep 4xe Charger Installation Guide

After purchasing the above chargers for your Jeep 4xe, the next step is the installation, Improper installation can pose serious risks of fire, electrical shock, and even injury, as professional EV charger installers we have first-hand experience and training in wiring the Jeep 4xe branch circuit wiring that meets safety standards.

The Jeep 4xe supports split-phase EV charging, accommodating both Level 1 (120V) and Level 2 (240V) options. For optimal performance, we recommend investing in a smart Level 2 EV charger for the Jeep 4xe. This allows for faster charging (approximately 2-4 hours for a full charge) when connected to a standard 240V split-phase electrical setup, utilizing two hot wires along with neutral and ground. In contrast, a Level 1 EV charger operating on 120V provides slower trickle charging, taking up to 12 hours to fully charge the Jeep 4xe.

In this guide, we will help you assess your existing electrical system to see if it can handle the additional load of a Jeep 4xe Level 2 charger, and also help you evaluate your system capacity, and recommend upgrades and accessories to improve your Jeep 4xe charging experience.

Purchase Compatible EV Charger: Best Jeep 4xe Charger

To charge the Jeep 4xe efficiently, you’ll require a compatible J1772 Level 2 charger capable of delivering 32 amps as the Jeep onboard charger limits the current draw to 32A on the 4xe. This setup will fully charge the Jeep 4xe’s 17 kWh lithium-ion battery in just two hours.

Below are some recommended chargers for the Jeep 4xe, offering built-in controls to set the output amperage specifically to 32 amps for optimal charging performance.

The on-board charger (OBC) converts incoming AC (Alternating Current) electricity to DC (Direct Current) to replenish the 17 kWh lithium-ion battery. The DC converter facilitates efficient power transfer between the AC charger and the OBC.

Consider installing your charger on a dedicated 40-amp circuit breaker for optimal safety and performance. Adhering to the 80/20 rule ensures your electrical system isn’t overloaded during charging. This rule dictates that circuits supplying continuous loads, such as EV chargers, should not exceed 80% of their capacity to prevent overheating and ensure safe operation.

Professional installation of the Jeep 4xe charger should mirror the electric vehicle branch circuit shown below:

Electrical Panel Assessment

When assessing the electrical panel for installing a 32-amp Jeep 4xe charger, it’s crucial to ensure safety and compatibility with your home electrical system. The electrical panel should have a breaker slot that should accommodate a 40-amp dedicated circuit breaker.

The electrical panel should also have a Wireway or “wire channel” that can neatly route and organize 8 AWG electrical wires from the main electrical panel to the 40 amps EV charger, and from the 40 amps to the knockouts or “cable exit points.” directing the 8AWG wires to the Jeep 4xe charger NEMA outlet.

For Jeep 4xe owners who have purchased a “dumb charger” such as the Grizzle E-Classic and would like to have smart EV charging features, the electrical panel should be able to accommodate smart meters for EV charging smart functions, and their sensors.

For Jeep 4xe owners who would like to integrate renewable energy EV charging the electrical panel should be able to accommodate a transfer switch, smart meters, and renewable energy sensors and cables connecting the accessories.

The diagram below shows an electric vehicle branch circuit for connecting a Jeep 4xe charger with renewable energy sources.

The system includes a solar panel array, a solar charger, a transfer switch, an emergency power off (EPO) button, a shunt trip breaker, a level 2 EV charger, and a Jeep Wrangler 4xe. The diagram also shows the electrical panel, current sensors, smart meter, incoming solar feed, solar sensors, main breaker, grounding connections, and conduit.

Electrical Panel Upgrade

After the electrical panel assessment you might need an electrical panel upgrade, depending on the electrical panel space availability, and also electrical compatibility, here is a guide on some of the factors that might require an electrical panel upgrade to accommodate your Jeep 4xe charger.

A 100 amps electrical panel is enough to accommodate your Jeep 4xe charger installations, depending on the home electrical panels installed, there should be enough amperage from the 100 amps electrical panel main electrical panel to accommodate a 40 amps dedicated circuit breaker.

If your main home electrical panel is heavily loaded with electrical accessories, you have two options: upgrade to a larger capacity panel, such as a 200-amp panel, or install a dedicated EV charging subpanel.

Installing a Jeep 4xe Charger on Your Home’s Electrical Panel

If your main electrical panel can accommodate a 40-amp circuit breaker, has an available slot, and sufficient space for 8 AWG wires, you can install your Jeep 4xe charger directly in the panel. Consider additional EV charging accessories to optimize your charging experience, such as renewable energy charging options and smart meters for enhanced management capabilities.

Depending on your aftermarket Jeep 4xe charger specifications, you have two options for installation on your main electrical panel: Plug-in and hardwired Jeep 4xe chargers.

Plug-in Jeep 4xe Charger Home’s Electrical Panel Installations

A plug-in Jeep 4xe charger offers convenient installation by simply plugging into a compatible outlet, typically a NEMA 14-50 or NEMA 6-50 receptacle. This setup is straightforward and suitable for locations where easy accessibility to an outlet is available near the charging station.

A plug-in Jeep 4xe charger allows for flexibility in relocating the charger if needed and is often favored for its simplicity in setup and use.
